Hacked Drones and Busted Logistics Are the Cyber Future of Warfare
“If you think any of these systems are going to work as expected in wartime, you’re fooling yourself.”
That was Bruce’s response at a conference hosted by U.S. Transportation Command in 2017, after learning that their computerized logistical systems were mostly unclassified and on the internet. That may be necessary to keep in touch with civilian companies like FedEx in peacetime or when fighting terrorists or insurgents. But in a new era facing off with China or Russia, it is dangerously complacent.
Any 21st century war will include cyber operations. Weapons and support systems will be successfully attacked. …
Why Was SolarWinds So Vulnerable to a Hack?
It’s the economy, stupid.
Early in 2020, cyberspace attackers apparently working for the Russian government compromised a piece of widely used network management software made by a company called SolarWinds. The hack gave the attackers access to the computer networks of some 18,000 of SolarWinds’s customers, including U.S. government agencies such as the Homeland Security Department and State Department, American nuclear research labs, government contractors, IT companies and nongovernmental agencies around the world.
It was a huge attack, with major implications for U.S. national security. The Senate Intelligence Committee is scheduled to …
The US Has Suffered a Massive Cyberbreach. It’s Hard to Overstate How Bad It Is
This is a security failure of enormous proportions – and a wake-up call. The US must rethink its cybersecurity protocols
Recent news articles have all been talking about the massive Russian cyber-attack against the United States, but that’s wrong on two accounts. It wasn’t a cyber-attack in international relations terms, it was espionage. And the victim wasn’t just the US, it was the entire world. But it was massive, and it is dangerous.
Espionage is internationally allowed in peacetime. The problem is that both espionage and cyber-attacks require the same computer and network intrusions, and the difference is only a few keystrokes. And since this Russian operation isn’t at all targeted, the entire world is at risk—and not just from Russia. Many countries carry out these sorts of operations, none more extensively than the US. The solution is to prioritize security and defense over espionage and attack…
How Hackers and Spies Could Sabotage the Coronavirus Fight
Intelligence services have a long history of manipulating information on health issues, and an epidemic is especially tempting for interference. Why aren’t we better prepared?
The world is racing to contain the new coronavirus that is spreading around the globe with alarming speed. Right now, pandemic disease experts at the World Health Organization (WHO), the U.S. Centers for Disease Control and Prevention (CDC), and other public-health agencies are gathering information to learn how and where the virus is spreading. To do so, they are using a variety of digital communications and surveillance systems. Like much of the medical infrastructure, these systems are highly vulnerable to hacking and interference…
Who Is Publishing NSA and CIA Secrets, and Why?
There’s something going on inside the intelligence communities in at least two countries, and we have no idea what it is.
Consider these three data points. One: someone, probably a country’s intelligence organization, is dumping massive amounts of cyberattack tools belonging to the NSA onto the Internet. Two: someone else, or maybe the same someone, is doing the same thing to the CIA.
Three: in March, NSA Deputy Director Richard Ledgett described how the NSA penetrated the computer networks of a Russian intelligence agency and was able to monitor them as they attacked the U.S. State Department in 2014. Even more explicitly, a U.S. ally—my guess is the U.K.—was not only hacking the Russian intelligence agency’s computers, but also the surveillance cameras inside their building. “They [the U.S. ally] monitored the [Russian] hackers as they maneuvered inside the U.S. systems and as they walked in and out of the workspace, and were able to see faces, the officials said.”…
Testimony at the U.S. House of Representatives Joint Hearing “Understanding the Role of Connected Devices in Recent Cyber Attacks”

Before the
U.S. House of Representatives
Committee on Energy and Commerce

Joint Hearing Entitled
“Understanding the Role of Connected Devices in Recent Cyber Attacks”
November 16, 2016

Good morning. Chairmen Walden and Burgess, Ranking Members Eshoo and Schakowsky, members of the committee: thank you for the opportunity to testify on this matter. Although I have an affiliation with both Harvard University and IBM, I am testifying in my personal capacity as a cybersecurity expert and nothing I say should be construed as the official position of either of those organizations…
Someone Is Learning How to Take Down the Internet
Over the past year or two, someone has been probing the defenses of the companies that run critical pieces of the Internet. These probes take the form of precisely calibrated attacks designed to determine exactly how well these companies can defend themselves, and what would be required to take them down. We don’t know who is doing this, but it feels like a large a large nation state. China and Russia would be my first guesses.
First, a little background. If you want to take a network off the Internet, the easiest way to do it is with a distributed denial-of-service attack (DDoS). Like the name says, this is an attack designed to prevent legitimate users from getting to the site. There are subtleties, but basically it means blasting so much data at the site that it’s overwhelmed. These attacks are not new: hackers do this to sites they don’t like, and criminals have done it as a method of extortion. There is an entire industry, with an arsenal of technologies, devoted to DDoS defense. But largely it’s a matter of bandwidth. If the attacker has a bigger fire hose of data than the defender has, the attacker wins…
Hacker or Spy? In Today's Cyberattacks, Finding the Culprit Is a Troubling Puzzle
The Sony hack revealed the challenges of identifying perpetrators of cyberattacks, especially as hackers can masquerade as government soldiers and spies, and vice versa. It’s a dangerous new dynamic for foreign relations, especially as what governments know about hackers – and how they know it – remains secret.
The vigorous debate after the Sony Pictures breach pitted the Obama administration against many of us in the cybersecurity community who didn’t buy Washington’s claim that North Korea was the culprit.
What’s both amazing—and perhaps a bit frightening—about that dispute over who hacked Sony is that it happened in the first place…
The Government Must Show Us the Evidence That North Korea Attacked Sony
American history is littered with examples of classified information pointing us towards aggression against other countries—think WMDs—only to later learn that the evidence was wrong
When you’re attacked by a missile, you can follow its trajectory back to where it was launched from. When you’re attacked in cyberspace, figuring out who did it is much harder. The reality of international aggression in cyberspace will change how we approach defense.
Many of us in the computer-security field are skeptical of the U.S. government’s claim that it has positively identified North Korea as the perpetrator of the massive Sony hack in November 2014. The FBI’s evidence is circumstantial and not very convincing. The attackers never mentioned the movie that became the centerpiece of the hack until the press did. More likely, the culprits are random hackers who have …
We Still Don't Know Who Hacked Sony
Welcome to a world where it's impossible to tell the difference between random hackers and governments.
If anything should disturb you about the Sony hacking incidents and subsequent denial-of-service attack against North Korea, it’s that we still don’t know who’s behind any of it. The FBI said in December that North Korea attacked Sony. I and others have serious doubts. There’s countervailing evidence to suggest that the culprit may have been a Sony insider or perhaps Russian nationals.
No one has admitted taking down North Korea’s Internet. It could have been an act of retaliation by the U.S. government, but it could just as well have been an …
